The lady clearly got on the cock of the sex-starved male! See with what pleasure and strength he fucks her, and besides when they started it was a bright day outside the window, and in the final shots of the video outside the window at night! How many hours in a row did he pull on the lady?
Not just rolled, but just really rolled, even to the point of squealing, so I think it's not surprising that it looks that way, fucked her bald, as it should be, well done for sure.
